The common English name of storage components is "Memory", the original meaning is memory, recall meaning, translated into Chinese will be called memory, storage, with the continuous development of technology, "Memory" evolved a product called "Flash Memory" (flash memory), after the new century, flash memory has basically become the main storage carrier of U disks and solid-state drives. Therefore, the official name of the U disk should be called USB flash drive, and the product that I experienced with you today is the new U366 USB flash drive of Jiaoxia, and the sequential reading speed exceeded 200MB / s, which was very unexpected.
From the moment I arrived at the U366, I remembered these storage products in my hand, which are mainly divided into two categories, one is storage space expansion and file backup, such as desktop hard disk, Baidu network disk, mobile phone cloud service (cloud disk), they mainly help me store and backup data files on the computer and mobile phone. Another category is mainly responsible for the mobile transfer of data, such as U disks and mobile hard disks, which is convenient for the transfer and use of some important data files between different platforms such as notebooks, desktops, and game consoles.
Due to the inherent advantage of the small and lightweight body, the U disk is a close-fitting mobile storage tool that I use more often, and in this regard, the armored man U366 has a significant advantage, it is much smaller and lighter than the USB stick I have used or seen before, weighing only 5.6 grams.
As I mentioned earlier, due to the small body, the U disk has always been a storage tool that I put in the pocket and the small backpack to use, in order to enhance the experience of close-fitting use, the armored man U366 also adopts the design of the hollow hanging ring, which is convenient for people to pin it to the keychain, so that people can carry it more safely and less easily lost.
USB flash disk as a kind of flash memory, the structure of the fuselage and composition and most flash products are similar, mainly composed of the main control chip and flash memory chip. As an important part of flash memory chips, flash memory particles play a vital role in the stability of U disks. In order to maintain the stability of the U disk for a longer time, the flash memory particles of the U366 use the flash memory particles of the original Japanese factory, which are of higher quality and basically have no dead pixel units, ensuring that the U disk can run stably in a long time and high frequency.
As the saying goes, "no one is perfect, gold is not enough", the U disk is small enough, but it is precisely because of the fuselage space that the speed limit of the U disk is limited to a certain extent. And the U disk "out of the same door" of the mobile solid-state drive (PSSD), its main control chip and flash memory chip is much more complex, and PSSD due to the structure of the circuit board, the power supply is more stable, the transmission speed is also faster. So is it difficult to improve the transmission speed of the U disk? There are also ways to do it, it depends on the manufacturer is reluctant to put down heavy costs to pile up materials, like armored man U366, the interface protocol of the U disk has been upgraded, becoming USB 3.2 Gen 1, and at the same time backward compatible with USB 3.1, 3.0, 2.0.
With the support of USB 3.2 Gen 1 interface protocol, the sequential read speed of the armored U366 64GB version can be as high as 100MB/s, and the 128GB version is as high as 200MB/s, for this reason, we used the ATTO Disk Benchmark to test the speed of the armored U366 128GB version, and found that its sequential reading speed is as high as 232.73MB/s, and the sequential write speed is as high as 35.51MB/s. The peak speed is about 10% higher than the official claim of 200MB/s.
In general, the speed of test software testing, because it is tested in a more ideal environment, so the speed will inevitably be a little higher, and in actual use, the speed may be slightly slower due to the difference in the environment. In order to more fully experience the read and write speed of the armored U366, we pulled a multi-gigabit-sized high-definition video from the U disk to the computer desktop, and found that the reading speed of the armored U366 was maintained at about 229MB/s, and the entire speed curve was very flat. From the entire test, it can be seen that in actual use, the speed of the armored man U366 is not much different from the peak speed officially declared, basically consistent, and the speed is still very stable as a whole.
In the past, when I used removable storage products, I often used a mobile hard disk for large files and high transfer speed requirements, and A U disk was used for small files and low transfer speed requirements. But the emergence of armored man U366, a little change my habits, 128GB of large space is enough to store many large files, and the peak reading speed of 200MB/s+ is generally quite enough. Small size, light weight, large capacity, fast speed, such a U disk is indeed to a certain extent more fragrant than the mobile hard disk.
